I think it makes sense to see the number of executed/skipped/failed/etc.
tests with the coverage report as they are directly related (if you add
more tests that usually increase the coverage, if you remove some, the
coverage will also drop).
Plus we didn't really had any complaints about having that (most people
doesn't even know about gcov).
